Public Policies for Healthy Eating: The Portuguese Experience with the Taxation of Sugary Drinks

Over the past decade, Portugal has increasingly focused on public policies that promote healthy eating, driven by growing concerns about the population’s health and its social, economic, and political effects. These policies aim to reduce unhealthy eating habits, which are major risk factors for disease, and to reduce the overall disease burden. Tax measures are specifically intended to curb the consumption of foods high in sugar, salt, and saturated fats to prevent chronic non-communicable diseases such as obesity, type 2 diabetes, and cardiovascular disease. This article analyzes the measures adopted in Portugal to reduce sugar consumption and examines their effects on tax revenue and consumption volume. Using document analysis, the results indicate a decrease of 3853 tons in sugar consumption and tax revenue of 432 million euros from taxing sugary drinks and sweeteners since 2017. Although significant progress has been made, including product reformulation to reduce sugar content, challenges remain. It is essential to continue and expand these policies to other products, along with ongoing impact assessments, to foster a healthier future in line with the World Health Organization’s guidelines for 2030.
